Landcover Maps

 Landsat Thematic Mapper (TM) Satellite Imagery (30-meter resolution) was used to identify upland land cover using a combination of classification techniques. Image classification techniques were applied along with ground truth information to classify image signatures into 15 classes (Open water, wetlands {defined by National Wetland Inventory}, Riparian Vegetation – Peat Bog, Riparian vegetation – Cattails, Forested – Deciduous, Forested – Evergreen, Forested – Mixed, Introduced Grassland, Native Disturbed Grassland, Native Undisturbed Grassland, Hayland, Cropland, Barren Land, Shrub, and Urban). Image acquisition dates were from Spring and Fall 2000 and 2001.

Grassland and woodland information in these maps were generated with GIS modeling techniques and represents the percent of landscapes comprised of grassland or woodland within all potential home ranges of nesting mallard hens. A moving window technique was used to calculate the amount of grassland or woodland habitat within 2 miles of each cell. Digital data processing, analysis, and hardcopy output were performed with Arc/Info GIS software (version 8.0.2) on a Windows NT workstation. These maps were produced as part of a joint project between the U.S. Fish and Wildlife Service, Habitat and Population Evaluation Team, Fergus Falls, Minnesota, and the Ducks Unlimited Great Plains Regional Office, Bismarck, North Dakota.
